Abstract

The dual-specificity tyrosine phosphorylation-regulated kinase 2 (DYRK2) regulates the induction of apoptosis and DNA repair, metastasis inhibition, cell cycle G1/S transition, protein scaffold stability for E3 ligase complexes, and embryogenesis. Owing to these functions, DYRK2 is thought to regulate tumorigenesis, and its function in cancer has been investigated. Notably, DYRK2 has been reported to function as a tumor suppressor; however, it has also been reported to act as an oncogene in some cancers. This discrepancy makes it difficult to elucidate the conserved functions of DYRK2 in cancer. Here, we reviewed the functions of DYRK2 in various cancers. Patient tissue samples were evaluated for each cancer type. Although some studies have used cell lines and/or xenografts to elucidate the mechanism of DYRK2 function, these studies are not sufficient to understand the role of DYRK2 in cancers. In particular, studies using genetically modified mice would help us to understand the reported functional duality of DYRK2 in cancer.
